Answer:
4.90 moles of
will produce (9.8) moles of
,
(4.90) moles of
and
(39.2) moles of 
Explanation:
From the question we are told that
The number of moles of is 
The formation reaction of
is
From the reaction we see that
1 mole of
is formed by 2 moles of
1 mole of
and 4 
This implies that
4.90 moles of
will produce (2 * 4.90) moles of
,
(1 * 4.90) moles of
and
(8 * 4.90) moles of 
So
4.90 moles of
will produce (9.8) moles of
,
(4.90) moles of
and
(39.2) moles of

Answer:
50.96g
Explanation:
Given parameters:
Number of moles of H₃PO₄ = 0.52moles
Unknown:
Mass of the compound = ?
Solution:
To find the mass of the compound:
Mass = number of moles x molar mass of H₃PO₄
Molar mass of H₃PO₄ = 3(1) + 31 + 4(16) = 98g/mol
Mass = 0.52 x 98 = 50.96g
The components are not permanently together. They can be separated and thats why its a mixture.
